Section 7 Environmental loads for unrestricted worldwide transit condition

7.1 Dynamic load cases and dynamic load combination factors for strength assessment

7.1.1  General.
  1. For the scantling requirements, the dynamic load cases are to be applied in accordance with the design load sets for the design load combination S + D. The simultaneously acting dynamic load cases are to be derived using the dynamic load combination factors given in Pt 10, Ch 4 Dynamic Load Combination Factors for unrestricted world wide transit.
  2. The Dynamic Load Combination Factors (DLCF) are dependent on the longitudinal position being considered. Tables are given in Pt 10, Ch 4 Dynamic Load Combination Factors for the longitudinal positions specified in Figure 2.7.1 Illustration of structural regions for DLCF Tables, for light load and deep load draughts.
  3. For the strength assessment by FEM, the simultaneously acting dynamic load cases are to be derived using the dynamic load combination factors given in Pt 10, Ch 4 Dynamic Load Combination Factors for unrestricted world wide transit.


    Note 1. Dynamic load cases for the mid and aft cargo tank region are applicable to tanks and spaces for the mid and aft cargo tank region.
    Note 2. Dynamic load cases for the aft end region are applicable to machinery spaces and other spaces aft of the mid and aft cargo tank region.
    Note 3. Dynamic load cases for the forward end region are applicable to tanks and spaces with their longitudinal centre of gravity position forward of 0,85L from AE. and forward the mid cargo tank region.
